This paper presents an updated foundation for process selection based on routinely measured parameters of particles (turbidity) and organic matter content (UV254, color and TOC). The distinction between mineral and non-mineral turbidity is addressed. Processes considered include direct filtration, conventional sedimentation, dissolved air flotation and contact clarification. The results of this paper are based on a survey of currently operating facilities, pilot studies, theory and North American experience. Recommended guidelines for process selection as a function of raw water TOC, color and turbidity are presented. Figures to aid process selection based on source water quality are provided. filtration, flotation, NOM, particles, sedimentation, treatment selection This content is only available as a PDF. © IWA Publishing 2009 You do not currently have access to this content.
